Description

By default, all tests in the mini-cluster don't run with Kerberos enabled. This seems bad for coverage as a lot of users of Impala actually run with Kerberos enabled. Given that we already have a BE test (https://github.com/apache/impala/blob/master/be/src/rpc/rpc-mgr-kerberized-test.cc) which creates a min-kdc on the fly and issues some RPCs, it may be helpful to look into re-using some of those code to set up a Kerberized environment by default for the mini-cluster testing.
